What is an undesirable reaction?

undesirable reactions - sometimes also called adverse reactions to drugs, unfavorable drug, adverse effect or adverse effect - is the reaction between a person and the drug or other type of drug that is usually unintended and negative. Unlike a side effect that may be unintended but potentially positive, undesirable reactions are almost always negative and can have a number of different causes and levels of severity. In many areas, government agencies require thorough testing of a new drug or pharmaceutical product to ensure product safety and try to discover any adverse effects than the product widely available to the public. Dose -dependent reactions are usually predictable and these types of reactions can usually be re -established in an experimental or laboratory environment with reliable results. Since research and understanding of pharmacology have improved over the years, these types of reactions have become more common, because fewer reactions are left unexplained.Understanding these types of reactions is particularly important because it can better provide less random cases of undesirable reactions to the drug.

idiosyncratic reactions, however, are not dependent on dose and are usually unpredictable. This type of undesirable reaction may not be able to easily replicate in experiments or studies. These are often allergic reactions in which a particular process in which the body responds negatively to the medicine is not fully understood, or where no clear common companions among entities with such undesirable reaction cannot be determined. Idiosyncratic reactions may be the most problematic for pharmaceutical society, as the most difficult to understand can be fully understanding and can lead to unintentional illnesses or death.

The level of severity of the undesirable reaction may change significantly and depends on the medicine and how it interacts with the body. Different organizations use a number of different standards, with different language and specificsconcerning each level of severity. Usually the word "serious" is used to describe a potentially fatal or life -threatening reaction that can lead to hospitalization or disability, even if it is sometimes used "deadly". "Serious" is often used as a modified term that denotes a sliding scale such as "low severity" or "high severity" depending on how unpleasant or painful can be a reaction.

In the United States, food and drug administration usually supervises drug and drug release to ensure the safety of these products. The European Agency for Drugs represents the European Union to investigate any possible reactions involving medicine. On an aglo -scale scale, the World Health Organization monitors various pharmaceutical products for potential adverse effects.
